Abstract: An apparatus and a method for transmission in an OFDM(Orthogonal Frequency Division Multiplexing) communication system are provided to transmit data by modulating the data transmitted to each repeater into signals with different amplitudes and different phases. A base station(100) selects a reference repeater(110) and a cooperation repeater(120) and then transmits data to the selected repeaters. The reference repeater receives the data from the base station, and modulates phase and signal amplitude of the data using a modulation coefficient corresponding to the reference repeater and then transmits the data to a destination terminal through space overlapping. The cooperation repeater receives the data from the base station, and modulates phase and signal amplitude of the data using a modulation coefficient corresponding to the cooperation repeater and then transmits the data to a destination terminal through space overlapping. A terminal(150) detects the data from the reference repeater and the cooperation repeater through maximum likelihood(ML) detection.

Abstract: A gate driver and a display apparatus having the same are provided to prevent an abnormal operation of a gate driver and the display apparatus by outputting a carry signal to a carry terminal irrespective of an abnormal gate signal. A gate driver includes plural stages. Each of the stages includes a pull-up unit(151), a carry unit(158), a pull-down unit(152), a pull-up driver(153), a ripple prevention unit(154), and a repair unit(155). The pull-up unit generates a current stage gate signal. The carry unit generates a current stage carry signal. The pull-down unit receives a next stage gate signal from one of next stages and discharges the current stage gate signal. The pull-up driver receives a previous stage gate signal from one of previous stages, turns on the pull-up and carry units, and turns off the pull-up and carry units in response to the next stage gate signal. The ripple prevention unit connected to an output electrode of the pull-up unit prevents a ripple of the current stage gate signal. The repair unit blocks supply of an abnormal signal from the output electrode of the pull-up unit to a control electrode of the carry unit.

Abstract: A method and an apparatus for determining a pilot pattern in a broadband wireless access communication system are provided to reduce a signaling overhead by switching the pilot pattern in a frame unit. An apparatus for determining a pilot pattern in a broadband wireless access communication system includes an OFDM(Orthogonal Frequency Division Multiplexing) demodulator(206) and a pilot pattern determining unit(200). The OFDM demodulator performs an FFT(Fast Fourier Transform) on a received signal and generates data in a frequency domain. The pilot pattern determining unit calculates a coherence bandwidth and a coherence time by using sub-carriers from the OFDM demodulator. The pilot pattern determining unit selects one of predetermined pilot patterns based on a ratio between the coherence bandwidth and the coherence time. An equalizer(210) compensates for channels of the sub-carriers from the OFDM demodulator and provides the compensated channel to the pilot pattern determining unit.
